如果您已經安裝了10.4 Sydney (2020年5月26日) ，那么安裝10.4 Sydney-Release 1需要完全卸載並重新安裝。作為卸載過程的一部分，您將看到一個保存設置的選項。這是默認啟用的。另外，還可以使用設置遷移工具保留設置。

Key Enhancements by product area in 10.4.1 10.4.1中按產品領域分列的主要改進

Supported Platforms 支持平台

RAD Studio now supports deploying apps on Windows Server 2019.

現在支持在 Windows Server 2019上部署應用程序。

IDE

Projects 項目

• Package AUTO libsuffix: packages can now have an automatic version suffix, instead of manually updating and specifying the right version suffix with each new release. (The compiler quietly supported this in 10.4, but full support for the feature in the IDE and package project settings is introduced in 10.4.1.) 包 AUTO libsuffix: 包現在可以有一個自動的版本后綴，而不是手動更新和指定每個新版本的正確版本后綴。(編譯器在10.4中悄悄地支持這個功能，但是在10.4.1中引入了對 IDE 和包項目設置中特性的完全支持。)
• The Pentium-safe FDIV compiler option is no longer shown in the Delphi compiler options. 奔騰安全的 FDIV 編譯器選項不再顯示在 Delphi 編譯器選項中
• The Projects pane context menu items that were no longer available after 10.3 (invoked by right-clicking on an empty area in the Projects pane) are now available via a drop-down in the Projects pane toolbar. “項目”窗格上下文菜單項在10.3之后不再可用(通過右鍵單擊“項目”窗格中的空白區域進行調用) ，現在可以通過“項目”工具欄下拉菜單項

Layouts 布局

• Improved support for multi-monitor desktop layouts for those using multiple editor windows across multiple screens 改進了對跨多屏幕使用多個編輯器窗口的多顯示器桌面布局的支持
• The floating form designer has been removed. Note that you can still have multiple edit windows including a form designer in a second window, and in fact, support for that has been enhanced. 已刪除浮動表單設計器。請注意，您仍然可以在第二個窗口中有多個編輯窗口，包括一個表單設計器，實際上，對該窗口的支持已經得到了增強
• When the IDE switches layout, such as to/from debugging, or to/from startup (e.g. when opening or closing a project), if the same layout is specified for both states, the layout won’t be applied. This avoids unnecessarily switching layouts. 當 IDE 切換布局時，如從調試切換到/從調試切換到/從啟動切換到/從啟動切換到(如在打開或關閉項目時) ，如果為兩種狀態指定了相同的布局，則不會應用布局。這樣可以避免不必要地切換布局
• Desktop layouts which cannot be applied (i.e. are floating layouts, no longer supported, see above) will be listed in gray in the Desktop Layout combo box in the title bar. When a floating layout is applied, the IDE will instead show a dialog. 無法應用的桌面布局(即浮動布局，不再受支持，見上文)將在標題欄的“桌面布局”組合框中以灰色列出。當應用浮動布局時，IDE 將顯示一個對話框
• Improved support for 4K monitors: IDE now correctly restores layouts on a 4K monitor in situations where the 4K screen is not scaled 改進對4K 顯示器的支持: IDE 現在可以在4K 顯示器上正確地恢復布局，在4K 屏幕沒有縮放的情況下
• If the IDE expects a project’s .dsk file but it does not find it, it opens using the default layout. 如果 IDE 需要一個項目的.dsk 文件，但是沒有找到它，它會使用默認布局打開

UI 用戶界面

• Options and other dialogs: 選項和其他對話框:
  • The Project Options, IDE Options, GetIt, and New Items dialogs now have scrollbar tracking (will move as you drag the scrollbar.) This includes scrolling with the mouse wheel 項目選項、 IDE 選項、 GetIt 和 New Items 對話框現在都有了滾動條跟蹤(將在拖動滾動條時移動)這包括用鼠標滾輪滾動
  • The Options dialog (environment options) used to always open to show settings for the Win64 target platform; now it opens according to the currently active platform. “選項”對話框(環境選項)過去總是打開以顯示 Win64目標平台的設置; 現在它根據當前活動平台打開
• Several listview controls, which can be difficult to read in the dark theme, have been replaced by the virtual treeview. 一些在黑暗主題中難以閱讀的 listview 控件已經被虛擬樹視圖所取代
• The guided tour was removed from the Welcome page 歡迎頁面上的導游已被刪除
• Several Object Inspector fixes, especially around flickering and selecting the wrong property 幾個對象檢視器修復，特別是在閃爍和選擇錯誤的屬性時
• Improved the selection of items on the Structure pane, including where you would click on an item and another item was selected 改進了“結構”窗格中的項的選擇，包括單擊項和選擇另一項的位置

General 

• Broadcast to devices’ is off by default. This always accessed the network on IDE startup, causing errors for some customers. Now that it’s disabled, (valid) network errors will only occur if you turn it on. “向設備廣播”默認是關閉的。這總是在 IDE 啟動時訪問網絡，導致一些客戶出錯。現在它被禁用了，只有當您打開它時才會發生(有效的)網絡錯誤
• The names of the 64-bit Windows debuggers (visible in the Attach To Process dialog) have been clarified to explain which is for Delphi and which for C++. This should help you choose which debugger to use when attaching to a process. 64位 Windows 調試器的名稱(在“附加到進程”對話框中可見)已經被澄清，以解釋哪些是用於 Delphi，哪些是用於 c + + 。這應該有助於您選擇在附加到進程時使用哪個調試器

Smaller but notable fixes 規模較小但值得注意的修復

• ‘Delete Invalid Paths’ should no longer remove valid paths. “刪除無效路徑”將不再刪除有效路徑
• Moving toolbars no longer presents issues. 移動工具欄不再提出問題

• The action editor used to draw images as black, which is resolved. 用於將圖像繪制為黑色的動作編輯器，該動作編輯器已解析
• Some IDE menus now draw correctly (e.g. popup menus in Audits); also some menus did not show the menu Checked state, but now do. 一些 IDE 菜單現在可以正確地繪制(例如審計中彈出菜單) ; 還有一些菜單沒有顯示 Checked 狀態，但是現在可以了
• The debug symbols search path now supports $(Platform) and $(Config) environment variables 調試符號搜索路徑現在支持 $(Platform)和 $(Config)環境變量
• The code editor used to let you select invalid encodings for a unit (applicable only to forms); these are now no longer available. 用於為單元選擇無效編碼的代碼編輯器(僅適用於表單) ; 現在不再可用
• An issue installing packages that presented as being unable to load a package, caused by packages with the filename case differing on disk and usually seen with large projects, has been resolved. 由於軟件包的文件名在磁盤上不同，通常在大型項目中可以看到，所以安裝軟件包時出現了無法加載軟件包的問題，這個問題已經得到解決

Delphi LSP/ Code Completion Changes Delphi LSP/代碼完成更改

• Code Insight now supports completing in a class declaration Code Insight 現在支持在類聲明中完成
• Significant performance work: 重要的工作表現:

• There are new options for controlling code completion, allowing you to tweak the functionality to behave much more similarly to classic completion. Read more about these settings 有控制代碼完成的新選項，允許您調整功能，使其行為更接近於經典的完成。閱讀更多關於這些設置的信息here 這里.
• When filtering code completion as you type, the matching characters are now optionally drawn underlined. 在鍵入篩選代碼完成時，匹配字符現在可以選擇地繪制帶下划線的字符
• Class completion settings have been moved to the Code Insight settings page 類完成設置已移動到“代碼洞察”設置頁

• When code completion’s list was set to sort by name instead of scope, selecting an item inserted the wrong text. This is fixed. 當代碼完成的列表被設置為按名稱而不是范圍排序時，選擇一個插入錯誤文本的項。這是固定的
• 10.4.1 also includes all fixes from 10.4 Patch 2, such as not inserting () braces when they already exist, pressing Space not selecting the current completion, completion lagging, and then not entering text correctly, Error Insight in the Structure pane lagging by a keystroke, and so forth. 10.4.1還包括來自10.4補丁2的所有修復，例如當已經存在時不插入()括號，按空格鍵不選擇當前完成，完成滯后，然后不正確輸入文本，結構窗格中的錯誤洞察滯后於按鍵，等等

Code Insight for Large Projects 大型項目的代碼洞察力

The following fixes will be especially noticeable for large projects. Note the above memory usage and performance fixes are also very significant for large projects.

Delphi Language Delphi 語言

The 10.4.1 release improves the Delphi compiler in several areas. In particular the focus was on supporting the LSP code completion, and in improving the managed records quality, but we also addressed a few 10.4 regressions and unexpected changes (including issues with goto statements and other uncommon scenarios). There are some improvements in package references and C++ HPP files generation. The release also improves compiler performance in a few areas, optimizing unit names lookup and other internal searches, benefiting large projects. There are also a few code generation improvements (that is, cases in which the compiler can generate code that performs better).

10.4.1版本在幾個方面改進了 Delphi 編譯器。特別是重點是支持 LSP 代碼完成，以及提高托管記錄的質量，但我們也處理了一些10.4回歸和意外的變更(包括 goto 語句和其他不常見場景的問題)。在包引用和 c + + HPP 文件生成方面有一些改進。該版本還提高了編譯器在一些領域的性能，優化了單元名稱查找和其他內部搜索，使大型項目受益。還有一些代碼生成方面的改進(也就是說，編譯器可以生成性能更好的代碼)。
